As stated in the school course catalogue, calculators are required for all math courses. Students in Algebra 1 or Geometry may use a graphing calculator or a regular scientific calculator. Students in Algebra 2 or higher must have a graphing calculator. While the school cannot dictate which model of calculator a family purchases, Texas Instruments calculators are recommended. The recommended scientific calculator is the TI30XS and the recommended graphing calculator is the TI 83+ or TI 84+ (any version). It is each studentâ€™s responsibility to know how to use his/her personal calculator.
